Definitions

  • the process includes rotating a drum covered with a periodic array of rubber dots through a fluidized bed of electrically conductive spherical particles about the size of the rubber dots.
  • the particles adhere to the rubber dots and any excess particles on the drum are suctioned off. This leaves conductive particles only on the periodic array of rubber dots.
  • the periodic array of particles is ultimately transferred onto the adhesive side of a pressure sensitive adhesive tape.
  • the diameters of the conductive particles are about equal to or somewhat larger than the thickness of the adhesive layer.
  • the result is an adhesive layer on a backing, the adhesive layer embedded with an ordered array of single conductive particles.
  • U.S. Pat. No. 5,616,206 also discloses the mechanical ordering of single layer particle arrays.
  • a mask containing a periodic array of equally- sized holes is placed onto a transfer surface.
  • conductive particles all having about the same size, are swept across the mask.
  • the diameter of the particles is about the thickness of the mask, and a specified number of particles fits into each hole.
  • Removal of the mask exposes the transfer surface having an ordered single layer of conductive particles.
  • this ordered layer of particles is not transferred onto an adhesive layer to form a z-axis conductive adhesive. Rather, a separate adhesive layer is formed on each electrode pad of a circuit layer.
  • the circuit layer is then brought down on the conductive particles so that each adhesive layer of each electrode contacts a portion of the conductive particles. Particles adhere to each of the adhesive layers, and the circuit layer is ready to be electrically connected to a second circuit. Because the mask must be as thin as the particles, this method is not amenable to very small particles, especially those smaller than 10 or 20 ⁇ m in diameter. A mask that thin cannot be expected to have the mechanical properties required to keep the particles in place.
  • Ordered particle-cluster conductive adhesives are made by forming clusters of conductive particles, placing the conductive clusters in an ordered array, and adhering the clusters to an adhesive layer.
  • U.S. Pat. No. 5,087,494 (Calhoun et al.) discloses taking a flexible carrier film having a pre-fabricated pattern of pockets and filling the pockets with conductive particles. The particles reside solely in the pockets and not in the areas between the pockets. The particles in the pockets may also be bound together with a binder material. An adhesive layer is then formed on the carrier film over the particle- filled pockets. The adhesive may then be adhered to one surface of a circuit layer.
  • the pitch of an electrode pattern can become finer by reducing the gap between electrodes, reducing the size of the electrode pads, or both.
  • the size of the conductive particles, the possibility of extended particle strings or clusters, and the density of particles in the adhesive all place limits on the fineness of the electrode pattern pitch. Large particles and particle strings and clusters place a lower limit on the separation between electrode pads, while the density of conductive particles places a lower limit on the size of the electrode pads. Therefore, a need exists in the art for a single particle layer z-axis conductive adhesive that ensures no extended particle strings, allows the use of small conductive particles, and provides maximum particle loading for the desired particle spacing.
  • the preferred particles are solid metal particles. Solid metal ferromagnetic particles are hard and will not deform under pressures used to laminate circuit layers together. This is important because, if there are any variations in size among the particles, the larger particles that first make contact between a pair of electrodes may prevent smaller particles from making contact between other pairs of electrodes.
  • deformable metal particles can be used, or deformable polymeric particles coated with a metal can be used, the pressure used to laminate the circuit layers will tend to deform the larger particles that make first contact, thereby allowing smaller particles to also make contact and ensuring the reliability of all the connections across the circuit.
  • the anisotropic conductive adhesive of the present invention addresses these problems, especially for fine pitch circuits (those employing electrode spacings and electrode pads with dimensions measured in hundreds of micrometers or less).
  • the present invention provides an anisotropic conductive adhesive having a predetermined pattern of conductive particles in a single layer. The placement of the particles is mechanically constrained so that no extended particle strings can form. Thus, the spacing between circuit electrodes may approach the size of the particles in the adhesive. In addition, because the particles are arranged in an ordered pattern, the particle density remains high enough to accommodate very small electrode pads.
  • the present invention also covers a method of making the anisotropic conducting adhesive of the present invention.
  • the first step is to provide a tool having a low adhesion surface characterized by a plurality of dimples, each dimple having a length, a width and a depth, wherein the dimples have substantially the same depth.
  • the tool may be a release liner which is capable of being re-used or remaining with the adhesive as a backing.
  • the conductive particles are placed in the dimples in such a way that the conductive particles form a single layer in the dimples. Any conductive particles residing on the tool in areas between the dimples are removed.
  • an adhesive layer is formed on the low adhesion dimpled surface of the tool such that the conductive particles in the dimples adhere to the adhesive layer.
  • the adhesive layer is capable of being removed from the tool, carrying with it the conductive particles.
  • the adhesive may be laminated to a backing film having a low adhesion surface so that the anisotropic conductive adhesive may be handled or rolled up for convenient use, shipment and storage.
  • Fig. 1(b) is a cross-sectional view of the conductive adhesive shown in Fig. 1(a) taken along line lb.
  • Figs. 5(a) through (c) are schematic representations of the steps of electrically connecting two circuit layers according to the present invention.
  • Figs. 6(a) through (e) are micrographs of various particle arrangements according to the present invention.
  • FIG. 1(a) shows a top view of one embodiment of the anisotropic conductive adhesive of the present invention.
  • Anisotropic conductive adhesive 10 includes an adhesive layer 12 and conductive particles 16 adhered to adhesive layer 12. Conductive particles 16 are arranged in particle sites 14. Aside from conductive particles 16, adhesive layer 12 is substantially free of conductive material.
  • Preferred film adhesive compositions include thermoset-thermoplastic blends.
  • Thermoset resins useful in such blends include epoxies and cyanate-esters, as well as acrylates and methacrylates, urethanes, polyimides, and others.
  • Useful thermoplastics include phenoxy, polyester, polyvinyl butyral, polysulfone, polycarbonate and others.
  • these blends include a curative or catalyst for the thermoset resin.
  • Epoxies may be cured either with amines, imidazoles or organometallic salts. Similar organometallic salts have also been used for cyanate ester trimerization.
  • Other useful adhesive compositions include, for example, blends of liquid and solid thermosetting resins, or simple hot-melt systems.
  • conductive particles are positioned in discrete numbers and placed in an ordered array.
  • the particles are placed in an ordered array by mechanically constraining them in an ordered array of dimples having a chosen size.
  • the first step is to provide a tool having a plurality of such dimples arranged in a periodic array.
  • the dimples in the tool ultimately define the particle sites of the conductive adhesive.
  • the dimples are all about the same depth, which preferably corresponds to the average size of the conductive particles so that only one layer of particles can reside in any given dimple.
  • the width and length of the dimples is determined by the size of the particles and the number of desired particles per particle site.
  • the dimpled surface of the tool is preferably a low adhesion surface, for reasons discussed below.
  • conductive particles 16 are dispensed to substantially cover the surface of the tool. Particles 16 fall onto tool 38 in a random fashion, some particles filling the dimples, some particles residing in areas between the dimples, and some particles residing on top of other particles.
  • Tool 38 and particles 16 advance to drum 32.
  • Drum 32 is equipped with brushes 34 that sweep the surface of tool 38 as it passes.
  • Drum 32 rotates opposite the advancement direction of tool 38. The direction of motion for the drum and the tool are indicated by arrows in Fig. 4.
  • the length and stiffness of brushes 34 are chosen depending on the size and type of conductive particles used. Smaller particles require smaller brushes, and heavier particles may require stiffer brushes.
  • an optional backing film may be laminated to the conductive adhesive.
  • the backing film may be laminated to the non-particle side of the adhesive layer or to the particle side of the adhesive layer.
  • the face of the backing film is preferably a low adhesion surface so that the conductive adhesive can be easily removed for use at some later time. If the backing film has low adhesion surfaces on both faces, the conductive adhesive may be rolled up with the backing film in a form convenient for storage, shipment, and later use.
  • the tool itself may be made of a flexible film material having a low adhesion surface, thus acting as a release liner for the conductive adhesive.
  • the filling of the voids with excess adhesive layer material promotes adhesion by increasing the surface area of bonding. It also prevents shorting by ensuring that the voids are filled with insulating material.
  • any conductive particles residing in the void between electrodes tend to be pushed away from the electrodes, resulting in a "washing away” effect that reduces the possibility of particles or particle strings forming in the space between electrodes that can lead to shorting.
  • the conductive particles reside in a single layer on the adhesive layer, each conductive pathway between electrodes is through a single particle. This minimizes the number of contact surfaces that may increase the resistance of the connection. It also creates multiple single-particle pathways for a given electrode pair, thereby introducing redundancy that increases reliability. Examples

Abstract

L'invention concerne un adhésif conducteur anisotrope (10) possédant une couche d'adhésif et des particules conductrices (16) collées séparément à la couche d'adhésif, selon un motif ordonné. La taille des particules conductrices est au moins approximativement inférieure à l'épaisseur de la couche d'adhésif. L'invention porte aussi sur un adhésif conducteur anisotrope possédant une couche d'adhésif, des particules conductrices collées séparément à la couche d'adhésif, et une bande de protection anti-adhésive (28) possédant un réseau ordonné de dépressions (24). Les particules adhésives sont présentes en une seule couche, dans les dépressions. On produit l'adhésif conducteur anisotrope en plaçant les particules conductrices dans un réseau ordonné de dépressions se trouvant sur une surface faiblement adhésive. Une couche adhésive est ensuite placée par dessus de sorte que les particules conductrices adhèrent séparément à la couche d'adhésif. L'adhésif conducteur anisotrope peut être utilisé pour la connexion électrique d'électrodes disposées selon un espacement serré sur des couches de circuit opposées.
